1o claims. (oren-1s) VThis invention relates to electric sewing ma chine cabinets or tables and has for an object to. provide a sewing machine cabinet or table with means fory detachably supporting a footoperated .type of motor-controller inipos-ition for knee-operation, from which position the controller may be readily shifted to conceal the latter when not in use. The invention also aims to provide an `electric sewingmachine cabinetl or table which, when not in use, has the esthetic appeal of an attractive article of furniture, with no conspicuous elements of Amechanization and which when opened foruse will `permit of the operation of the sewing machine Amotor-controller either by knee or by'foot, at the will of the opera or.

With the above and other objects in View, as will hereinafter appeanthe invention comprises the devices, combinations, Vand arrangements of parts hereinafter set forth and `illustrated in the accompanying drawings of a preferred embodiment of the invention, from which the several features of the 'invention'and the advan# tages attained thereby willV be readily understood by those skilled in the art.

VIn the accompanying drawings, Fig. -1 is a front elevation of a drop-head sewing machine cabinet or table embodying the invention, Fig. 2 is a fragmentary horizontai section through one corner of the cabinet,'showing thev motor controller in concealed position. Fig. 3 is a transverse vertical section through the' cabinet. Fig. 4 is a transverse section through the controller unit and its support. Fig. 5 is aperspectiveview of the controller support and Fig. 6 is a perspectiveview'of the rear orbottom face of the con-1 troller casing.

In the preferred embodiment of they inven-` tion illustrated, the numeral I indicates the legs' head 6 is resting in its lowered position. v'lhej sewing head 'E haslmounted thereon a driving" motor 9 the pulley III of which is connected by a belt II to the balance wheel pulley l2 of the machine head. Y v

Mounted in the right-hand front corner of the cabinet by screws I3 isa bracket I4 having a short leg I5 and alonger leg I6 supporting the hinge pin I1'. The longer leg I6 has atits free end a tang I6 which is driven into the front wall 5 of the table to steady the bracket I4 and relieve the screws I3 of a certain amount of strain to which they would otherwise be sub-` jected. Y l

Mounted on the hinge pin I'I is a swingable controlier-supporting member I8 rin the form of a sheet metal plate having bent up marginal wall portion-s `I9 and overhang'ing lips 20 defining a slideway for reception of the longitudinal ribs ZI oi the casing 2 I of the conventional motor-controller having an operating pedal` 22 hinged atx-23 on the casing 2I and connected to the pull-rod 24 of the usual carbon compression type rh'costat 25 housed the casing 2l. A controller of this type is -disclosed in U. S.vPat ent No. 1,777,988, of Oct. 7, 1930. y

Mounted on one-ofthe sidewalls I9 of the controller support Ill,` within the controller-re-` ceiving siideway, is a leaf-spring 26 which' yieldingly urges the controller casing 2I-toward Vthe opposed side Wall I9, the width of the s'lideway 20 being somewhat greater than the width of the controller casing to permit of a certain amount of side play of the controller within thes1ide Way.

The controller casing 2l struck out fromA its bottom wall -atongue or lug 2l which en -V gages over the upper end of aninclined tongue ing plate I8f it is merely necessary to shift the controller laterally toward the leaf-spring 2B sumciently to disengage the lug 2I from the end of the inclined lug 28, whereupon the controller may be slid downwardly vout of the slideway inY the plate -I8 and placed upon the floor forfootoperation.Y To replace the controller in the supporting plate, it is merely necessary to insert ,the ribbed portion 2i of the controller casing in the: slidewayY of the supporting plate and Vsli-de the controller upwardly until the lug 2T sn-apsV past the inclined lug 26 and is locked by thellatter in position for knee-operation." l l When: the outt is not in use, the plate l8`-, tol gether with the controller 2l, may be swungupwardiy about the hinge-pin I1 tothe concealed position, shown in dotted lines in Fig. 1, within the cavity of the cabinet where it is retained by.Y

the entry ofthe rounded'neb 29 on the leg I6 into thehole 30 in one side wall I9 of the platel I8;

being yieldingly held there bythe spring 3l which` is carried by the plate Iand engages the legV I5" of the bracket HI.

The plate I8` has xed to its lower end a rubber `foot 32 which rests against one of thetable legs I when the controller is in pendant operative or. airline @sinon rig. I, in; which position the pedal 22 of the controller isaceess'ible for 'knee-r operation.

The controller is connected by a length of conductor cord 33 to the current-receiving plug 34 and islconnected in series with the sewing machine motor connector 35 and in multiple with the sewing machine light connector 36, in accordance with the usual practice. The conductor cord V33, which is long enough to reach to vthe controller when placed upon the floor for foot operation',V Y may be Vlooped. and held by the hook 31, Fig. 3,

forV knee operation. Y

when thercontroller is placed in the support I8 We are aware that we are not broadly the rst to mount a foot-operated motor-controller on aA sewing machine table in position for knee-opera- I .It win be obvious tov those` skilled in the art to ,which the invention appertains that modifications tion but, so far as we are aware, no one has heretofore Vaccomplished thisY result in a sewing machinelcabinet or'table which, when not in use, has 'the esthetic appeal of an attractive article Yof furniture and the motor-control mechanization of which is of a disappearing nature yet may be operated eitherby foot'or by knee( may' bemade in the details of construction and in the forms and relativearrangements of parts Awithoutdeparture from the spirit of the invention which is not limited to such` details and mat-v Y Yters of form or otherwise than the prior art and the appended claims may require.
